Shortly before 11 p.m. WCVB Channel 5, Wicked Local’s reporting partner, checked off Moulton as the winner with 66 percent of the vote.

The Salem Democrat, decorated Marine Corps veteran and Harvard graduate handily won a third two-year term, defeating a pair of challengers, Rockport independent Mary J. Charbonneau, who walked away with 3 percent of the vote, and Beverly Republican Joseph Schneider, who garnered 31 percent of the vote.

“I’m grateful that you’ve given me the honor to serve you in Washington for two more years,” Moulton said in an emailed statement Tuesday night. “To everyone who knocked on doors, made calls, donated, rallied, marched, and voted: thank you. This victory is yours.”

Moulton admittedly spent most the election season traveling around the United States, stumping for 69 candidates whom his political action committee, Serve America, endorsed in swing districts across the country.

In the 2018 election season, Moulton has stood as an unmatched force. The two-term Democrat benefited from coordinated campaigns with Sen. Elizabeth Warren and Massachusetts Attorney General Maura Healey and a tremendous sum of money compared to that of his opponents.

According to the Center for Responsive Politics, Moulton raised $2.2 million and spent $2.4 million, while Schneider raised $226,017 and spent $181,950 and Charbonneau raised $382 and spent $254.

Schneider pounced at the opportunity to frame Moulton’s campaigning across the United States as building a political network for a future run for higher office. He also argued Moulton has done too little for the 6th District and veterans over his two-year term.

Moulton countered with a defense of his work, saying his district office closed 906 constituent cases in the past year, recouped over $700,000 that the federal government owed his constituents, helped veterans access services that they deserve and worked toward Lynn’s economic revitalization.

Over his four years in Congress, two presidents have signed a total of three bills with Moulton’s name on them. When it comes to lawmaking, a 2017 Lugar Center and Georgetown University McCourt School of Public Policy study put Moulton among the top 10 percent of bipartisan congressional lawmakers who introduce legislation alongside Republicans, ranking him 34 out the 427 members of Congress.

When the congressman did carve out time to campaign in the 6th District, it was in the 11th hour. He also largely ignored his opponents, debating Schneider only once, two weeks before the election. Charbonneau, an independent, was not invited to participate.

When he did hit the local campaign trail, Moulton largely talked about President Trump.

“I’ve been very public about how hard I’ve been working to win a Democratic majority in the House to put a check on this runaway [Trump] administration,” Moulton told Wicked Local editors in a late October interview.

He characterized Schneider as a reliable vote for the Trump administration and Republican Party. He called Trump’s signature legislation, the Tax Cuts and Jobs Act of 2017, a $1.5 trillion tax bill (one he said Schneider supported), fundamentally amoral, benefiting the rich and bad economics. It would balloon the deficit even more and lead to the biggest manufactured debt crisis in American history, he said.

Despite a boom economy, Moulton has said rampant inequality exists. The American dream is slipping away, and he argued a vote for him would be one to keep the dream alive and available to everyone.

“What we need is people in Washington who have courage about the nation’s problems who are not going to say 'let's cuts taxes,' but especially for big corporations and rich donors who fund our campaigns,” Moulton said.

He also argued an experienced Democratic congressman is vital while an antagonistic president sits in the Oval Office. It’s a message - alongside Moulton’s two-term record - that seems to have resonated with voters on Tuesday.

“Together, we’ve made tremendous progress over these last four years. I believe we can do even more in these next two,” said Moulton. “The election is over. Now, the real work begins.”

On election night, Moulton did not hold a campaign watch party; he instead planned to address supporters and volunteers in an early morning “thank you breakfast” in Salem. During the day, he attended two election-related events in Beverly and Gloucester.

“He’s going to watch results come in between his home and campaign headquarters,” said Moulton’s campaign communication director, Matt Corridoni, Tuesday. “He will be talking to folks he’s endorsed across the country and congratulating [candidates] who win in Massachusetts.”
